ELECTRIC IMPLEMENT.

SPECIFICATION forming part of Letters Patent No. 295,652 dated March 25,1-884.

Application filed October 25, 1883. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR H. KINDER, of Boston, county of Suffolk,State of Massachusetts, have invented an Improvement in ElectricImplements, of which the following description,in connection with theaccompanying drawing, is a specification.

My invention'relates to an implement or apparatus in which an electricalcurrent is employed as the actuating-power for operating tools, theinvention being shown as embodied in a device'especially intended forperforating paper for making stamped patterns for embroidery and similarwork.

i The apparatus consists, essentially, of an electric motor composed ofa field-magnet and armature rotatedthereby, the shaft or arbor of thesaid motor being provided with a flywheel, and actuating by a suitablecrank or eccentric a rocking lever connected with a toolcarrying barreciprocated thereby, the said bar being guided in a passageconstituting a handle by which the entire apparatus may be moved aboutas desired, and the passage also being provided with a supporting-foot,which rests upon the material being perforated. The shaft of the motoris also provided with a chuck or clamp for holding small tools thatoperate with a rotary movement-such, for instance, as drills, gimlets,850.

The drawing shows in side elevation an electric implement or apparatusembodying this invention.

The motor consists of a field-magnet, a, supported upon a frame orplatform, I), having bearings c for the shaft d, upon which is mountedthe armature and commutator, the said magnet and armature being of anyusual type or construction, and having their terminals connected withbinding-posts e e, to be con nected with the poles of the battery orother generator of electricity by flexible conductors or wires,permitting the free movement of the entire apparatus in all directions.The supporting-platform b rests on or has connected with it aguide-tube, f, the outside of which is shown in this instance as shapedto constitute a handle, 9,120 be grasped and held firmly in the hand ofthe operator, and contains within it a vibrating bar, h, carrying avibrating too1,i, shown in this instance as a pointed rod or pin forperforating paper when supported on a yielding surface or pad. The bar his connected with a lever, is, pivoted in a lug, k, at the under side ofthe platform I), and connected at its end with a link, m, attached to aneccentric-strap, it, operated by aneccentric on the shaft (1 of themotor. The said shaft (1 is also provided with a tool-holding chuck orclamp, 0, for holding rotary 0perating-toolssuch, for instance, asdrillsand the other end of the magnet on may be provided'with a knob orhandle, 12, to enable the apparatus to be steadily held by both hands inusing it. The lower end of the guide-tube f is provided with asupporting-foot, recessed, as shown, to show the point of operation ofthe tool i, and made adjusta-ble'on the tube f, to regulate the depth towhich the tool 73 may penetrate the material on which the foot r rests.By the employment of the vibrating shaft h and connecting mechanism is mit between it and the rotating armature, as shown, the said vibratingshaft and tool carried by it is operated with a comparatively slow butvery powerful movement, much better adapted to that class of work forwhich the tool is intended than the more rapid but shorter and weakermovement produced by connecting the tool directly with a vibratingarmature.

The entire apparatus forms a very complete device for actuatingvibrating or rotary moving tools, as it has perfect freedom of movement,and can be held and guided by the hands of the operator, who is notrequired to devote any of his attention to the means for actuat ing thetools, as is the case when treadles or foot-power is used.

The apparatus may be used in many places I where it would not beconvenient to use devices fiXed upon a table.

I claiml. The field-magnet and its rotary armature and shaft andsupporting-platform therefor, combined with the guidetube connected withthe said platform, the vibrating rod for carrying a tool guided in thesaid tube, and the rocking lever fulcrumed on the said platform, andhaving one arm connected with the said rod, and its other arm connectedwith the armature-shaft, substantially as described.

'2. The electromotor having a rotary shaft,

having one arm connected with the said rod, and its other arm connectedwith the rotary shaft, substantially as described.

In testimony whereof I have signed my name .1 5 to this specification inthe presence of two subscribing witnesses.

ARTHUR H. KINDER.
